**Problem:**
When using adk in streaming mode, `usage_metadata.prompt_token_count` may be `None` which will emit log
```Invalid type NoneType for attribute 'gen_ai.usage.input_tokens' value. Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or a sequence of those types```

Skip setting span attribute if prompt token count is None

This change updates the VertexAiMemoryBankService to utilize the asynchronous interface provided by `vertexai.Client().aio`. This involves:
- Retrieving the async client via `_get_api_client().aio`.
- Awaiting calls to `generate` and `retrieve`.
- Using `async for` to iterate over the results of the `retrieve` method, as it now returns an async iterator

The filtering logic has been rewritten to identify invocation start points based on human user messages
